Connection Keeps Dropping Out and Reconnecting - New Install

I heard from TPG Eng this morning and if I heard right (because I still don't hear well on the phone) I can expect a TPG engineer to visit again, and another modem to try out - because the current one is faulty, evidently and according to NBN tech who visited.

Can you confirm a TPG engineer will be visiting, and a new modem will be sent? Or did I hear wrong?

There was no drop outs last night - I had come to expect them to start around 6pm after your techs sorted the wiring. But I am also told NBN has been down locally due to weather, with some remedial works on, and not many people are back online yet.

So I would like to monitor for another couple days to confirm issue is corrected, or have the line fault show again with more time and traffic. Make sense?
